Prerequisites for the High-Performance Analytics Transformations

The servers, libraries, and user IDs that are required by the High-Performance Analytics transformations are assumed to be registered in the same metadata repositories on the SAS Metadata Server. This is the usual configuration when SAS Data Integration Studio and SAS LASR Analytic Server are installed as part of a SAS Analytics solution.

An initial set of libraries might be configured when SAS Data Integration Studio and SAS LASR Analytic Server are installed as part of a SAS Analytics solution. This includes SAS Data in HDFS libraries and SAS LASR Analytic Server libraries. These libraries are used to connect to HDFS and the SAS LASR Analytic Server. Let SAS Data Integration Studio users know which libraries are available to them.

For more information about registering SAS Data in HDFS libraries and SAS LASR Analytic Server libraries, see the” Connecting to Common Data Sources” chapter in SAS Intelligence Platform: System Administration Guide.

Each user who wants to submit a job that includes a High-Performance Analytics transformation must log on to SAS Data Integration Studio with a special operating system user ID. This ID must be configured for Passwordless Secure Shell (SSH) on the machines in the High-Performance Analytics cluster. One way to do this is to configure the operating system user IDs of appropriate SAS Data Integration Studio users. The operating system user ID is specified in the metadata connection profile for the SAS Data Integration Studio user.
